Simulation CAD & Asset QA Engineer (3D Assets)

We’re hiring a CAD/3D Engineer to develop and validate simulation-ready 3D assets . This role focuses on creating high-fidelity models and performing QA/QC to ensure assets match real-world objects in geometry, scale, surface characteristics, and material definitions . You’ll also support integration into an existing Blender-based pipeline and help maintain modeling standards.

Key Responsibilities

1. CAD Modeling & Asset Development Build high-fidelity 3D models of vehicles (ground/air/sea) and infrastructure/environment assets. Create clean, simulation-ready meshes (STL/OBJ/FBX as needed) with correct scale, orientation, and naming. Maintain Levels of Detail (LOD) for performance and scalability. Model from technical references, drawings, images, and public/open-source materials.
2. Asset QA/QC & Validation (Primary Focus) Verify assets against references for dimensional accuracy, proportions, key features, and assemblies . Ensure mesh integrity : watertight/manifold (when required), correct normals, consistent topology, and no self-intersections. Validate and document surface/material properties used in simulation/rendering (e.g., material categories, roughness/metalness/specular conventions, surface smoothness). Establish QC checklists and acceptance criteria for assets (units, pivot/origin, LOD consistency, naming, hierarchy, metadata). Identify and resolve geometry/material issues causing artifacts in downstream rendering/simulation outputs.
3. Pipeline Integration & Automation Support Integrate assets into an automated Blender-based pipeline and standardized scene conventions. Use parameter-driven configs (e.g., YAML/JSON) as part of the asset ingestion workflow. Write small Python scripts/utilities for export automation and validation checks. Support minor fixes/maintenance to existing asset tooling and documentation.
4. Documentation & Standards Maintain asset preparation guidelines: modeling rules, export settings, QC procedures, and versioning practices. Create example assets/templates to help standardize future model creation.

Requirements

Must Have Strong CAD/3D modeling experience (SolidWorks / Fusion 360 / Rhino / Blender or similar). Strong understanding of mesh topology , geometric accuracy, and clean export practices. Experience exporting STL/OBJ (and ideally FBX/GLTF) with consistent scale and orientation. Blender experience (modeling + scene organization); basic knowledge of materials/shaders is a plus.

Ability to perform structured QA/QC using references (drawings, photos, specs) and produce clear validation reports. Basic Python scripting for automation/validation (mesh checks, naming rules, export helpers).

Nice to Have

Familiarity with ray-tracing/rendering workflows or physics-based simulation constraints. Experience with large assemblies, vehicles, or infrastructure-grade models. Git/version control and asset versioning discipline. Experience building internal standards/checklists for asset production.
